  • Method and structure for coupling two microcircuits
    Patent number: 7282776
    Abstract: A system in a package (SIP) or multi-chip module (200, 300, 400) (MCM) uses an electron beam (235, 335, 435) for electrically coupling between microcircuits (230, 330, 430) and (232, 332, 432). In one embodiment, the micro-circuits (230, 430) and (232, 432) can be configured in a side-by-side configuration. In another embodiment, the micro-circuits (330) and (332) can be configured in a chip-on-chip configuration. In yet another embodiment, the electron beam (435) can include a plurality of electron beams (436) and appear as ribbon shaped between two micro-circuits (430, 432). Further, the fabrication to form the electron source (234, 334, 434) and the deflector (261, 356, 461) can be at the final metallization step of the process.

    Abstract: Methods and apparatus are described relating to a crossbar which is operable to route data from any of a first number of input channels to any of a second number of output channels according to routing control information. Each combination of an input channel and an output channel corresponds to one of a plurality of links. The crossbar circuitry is operable to route the data in a deterministic manner on each of the links thereby preserving a partial ordering represented by the routing control information. Events on different links are uncorrelated.

  • Dynamic calibration of I/O power supply level
    Patent number: 7283070
    Abstract: An input/output interface is used to transmit data between a transmitting circuit and a receiving circuit. Selectively during both system startup and system operation, a known bit pattern transmitted by the transmitting circuit is compared to a received bit pattern. The received bit pattern may be seen at the receiving circuit or a voltage regulator that is used to control the power supply level of the input/output interface. Dependent on the comparison of the known bit pattern and the received bit pattern, a bit error rate across the input/output interface is determined, in response to which the voltage regulator adjusts the power supply level of the input/output interface.

  • Method and apparatus for offloading message segmentation to a network interface card
    Patent number: 7283522
    Abstract: One embodiment of the present invention provides a system that facilitates offloading message segmentation from a central processing unit onto a network interface card. The system operates by first receiving a TSO-send message at the network interface card, wherein the TSO-send message contains information about the message to be sent. Next, the system uses a header address from the TSO-send message to access a message header from memory using remote direct memory access. The system then uses a payload address from the TSO-send message to access a payload from memory that contains message data using remote direct memory access. Finally, the network interface card segments the payload into a set of maximum segment size (mss) segments and transmits the set of mss segments on the network.

  • Method and apparatus for constructing wired-and bus systems
    Patent number: 7284079
    Abstract: A large multimaster I2C bus system is partitioned into smaller bus segments. The bus segments are connected by bridges that isolate the segments and direct selected transactions and commands between the segments. The bridge may handle bus segment error conditions and particularly a hang on the Port B bus by attempting to cause any device on the bus segment to respond after the bus bridge has attempted to acquire the segment for a first predetermined period of time. If the bus responds within the first predetermined period of time, the bus bridge resets the bus segment.

  • Resonant detector for optical signals
    Publication number: 20070235651
    Abstract: An electronic receiver for decoding data encoded into light is described. The light is received at an ultra-small resonant structure. The resonant structure generates an electric field in response to the incident light. An electron beam passing near the resonant structure is altered on at least one characteristic as a result of the electric field. Data is encoded into the light by a characteristic that is seen in the electric field during resonance and therefore in the electron beam as it passes the electric field. Alterations in the electron beam are thus correlated to data values encoded into the light.

  • Computer-based presentation manager and method for individual user-device data representation
    Patent number: 7281060
    Abstract: Access to external service providers is provided through portlets, where each portlet accessible by a user is represented on the display of the user device. Through use of a dynamic content channel, e.g., a portlet, a highly customizable content page may be produced for any individual client system. When a portlet is selected on a user device, the content associated with the portlet is retrieved and automatically transformed into data that can be displayed by that user device. Thus, a particular user device is not limited to accessing content in a format identical to that associated with the user interface in use on the user device. Consequently, the user's ability to access a wide variety of content sources independent of the characteristics of the particular user device is further enhanced.

  • Authenticating legacy service via web technology
    Patent number: 7281139
    Abstract: A system and method for authenticating a legacy service using internet technology is disclosed. An authentication module is associated with the legacy server. Service requests from a user of the legacy server are passed to the authentication module. The authentication module generates a service request for a web server, requesting access to a protected page from the web server, and transmits the user's credentials to the web server. The web server attempts to access the protected server, which causes the web server to access a network-based authentication service to determine whether the user's credentials qualify for access to the protected page. The web server transmits a message back to the authentication module, which determines whether the user's credentials qualify for access the legacy server based on the message from the web server.

  • Using token-based signing to install unsigned binaries
    Patent number: 7281132
    Abstract: The present invention provides for token based signing of an unsigned binary which may be a stream of bits (e.g., 0's and 1's). The unsigned binary is signed using a secret key which resides in a token (e.g., a smart card), which makes the secret key available to the token holder. The unsigned binary is downloaded and verified for authenticity by the token coupled to a computing device. In one embodiment, the downloaded unsigned binary is encrypted. If the unsigned binary is authentic, it may be used to replace the prior firmware on that computing device.
